Ok, mystery solved, straight from pp 2-33 of the factory manual for '94MY
XJ/YJ, on command trac axles (ie, YJ):

Differential carrier is sealed on left (driver's) side at the carrier
bearing.

Differential is sealed at the right (passenger's, or disconnect) side on the
outside of the disconnect assy.

Thus Bill is correct, no seal at the inner disconnect needle bearing and the
5OZ added must be a pre-lube.

I stand corrected.

Then how can the outer seal leak?

I mean when they leak, they freaking pour it out if you are tipped
sideways.

This cannot be if there is an inner seal. (Don't even think about
telling me the inner seal must be blown on 'all' of the ones I have seen
or heard of needing an axle seal changed, I won't believe that for a
second)

Where is the dip stick or check hole for the shift motor oil?

The book cannot say 'toss a tablespoon or so' in there when opening it
up only.

The maintenance schedule does 'not' mention anywhere that you have to
check the oil level in the shift motor nor are any provisions made to do
so.

'Every' other fluid level in the Jeep has a way to check it.

Tell ya what, when I get a chance to help the next person who needs an
outer seal changed, I will get them to fill up the shift motor to see if
oil actually stays in it or the OP could do that just to make sure.
